Datacenter power management using AC and DC power sources

A computer program product embodied in a non-transitory computer readable medium for power control, the computer program product comprising code which causes one or more processors to perform operations of:

• providing an AC power distribution topology to a datacenter to provide one or more AC power sources to computing devices within the datacenter;
• providing a DC power distribution topology to the datacenter to provide one or more DC power sources to computing devices within the datacenter in addition to the AC power distribution topology;
• provisioning, using a software-defined power infrastructure, an uninterruptible power supply (UPS) to a rack of computing devices within the datacenter, wherein the UPS is capable of receiving the one or more AC power sources using the AC power distribution topology and the one or more DC power sources using the DC power distribution topology, and wherein the UPS includes multiple batteries spread across multiple data racks and uses the one or more DC power sources to load-share with the one or more AC power sources wherein load-sharing is enabled by a policy within the software-defined power infrastructure, wherein the policy dictates a mix of AC power from the one or more AC power sources and DC power from the one or more DC power sources;
• identifying AC power sources according to the policy and the mix;
• identifying DC power sources according to the policy and the mix;
• directing power from the AC power sources and the DC power sources according to the policy and the mix;
• evaluating the one or more DC power sources for energizing the DC power distribution topology;
• and
• connecting the one or more DC power sources to the UPS which is provisioned to the rack of computing devices, based on the evaluating and a datacenter power requirement.

A computer system for power control comprising:

• a memory which stores instructions;
• one or more processors attached to the memory wherein the one or more processors, when executing the instructions which are stored, are configured to:
• provide an AC power distribution topology to a datacenter to provide one or more AC power sources to computing devices within the datacenter;
• provide a DC power distribution topology to the datacenter to provide one or more DC power sources to computing devices within the datacenter in addition to the AC power distribution topology;
• provision, using a software-defined power infrastructure, an uninterruptible power supply (UPS) to a rack of computing devices within the datacenter, wherein the UPS is capable of receiving the one or more AC power sources using the AC power distribution topology and the one or more DC power sources using the DC power distribution topology, and wherein the UPS includes multiple batteries spread across multiple data racks and uses the one or more DC power sources to load-share with the one or more AC power sources wherein load-sharing is enabled by a policy within the software-defined power infrastructure that defines a mix of AC power and DC power when at least one of the AC power sources is fully operational;
• establish AC power sources and DC power sources to provide power to the UPS according to the mix defined in the policy;
• evaluate the one or more DC power sources for energizing the DC power distribution topology;
• and
• connect the one or more DC power sources to the UPS which is provisioned to the rack of computing devices, based on the evaluating and a datacenter power requirement.
